Well, there is stable and stablegen, as Jay already pointed out.
These can be used to generate persistent versions of almost any
data structure.

stabletable may have been an predecessor of the more general
stable package. I also found the attached documentation, which
seems to be missing on our web site.

I rather think that Critical Mass people have cleaned up the set
of packages a bit.

If you think it is useful in addition to stable and stablegen,
there's no reason why not to add it. Put it into m3-db.
If it's more or less code duplication, don't do it.

I cannot answer this question.
